Optical device and manufacturing method thereof

The invention provides an optical device and a manufacturing method thereof. The optical device includes a substrate and a plurality of optical structures. The substrate includes a plurality of photoelectric conversion elements. The plurality of optical structures are arranged on the substrate. Each optical structure corresponds to one photoelectric conversion element. Each optical structure includes a first portion and a second portion. The first portion has a first glass transition temperature. The second portion has a second glass transition temperature. The second portion introduces incident light into the photoelectric conversion element. The first glass transition temperature is greater than the second glass transition temperature. 本发明提供一种光学装置及其制造方法。该光学装置包括基板以及多个光学结构。该基板包括多个光电转换元件。多个所述光学结构设置于该基板上。每一光学结构对应一光电转换元件。每一光学结构包括第一部分与第二部分。该第一部分具有第一玻璃转移温度。该第二部分具有第二玻璃转移温度。该第二部分将入射光导入该光电转换元件。该第一玻璃转移温度大于该第二玻璃转移温度。
